Abstract

Polymerization of N-methylpyrrole and the transient redox behaviour of the polymeric film were studied by spectroelectrochemical methods in the presence of BF4-, ClO4- and PF6- in an acetonitrile solution containing 10 ± 1 ppm of water. The doping levels and the rate of absorbance changes at different potentials were determined and compared with those obtained for polypyrrole. In poly(N-methylpyrrole) BF4- behaves in a similar way to ClO4-, in contrast with polypyrrole. This is interpreted as evidence that the BF4--polymer interaction in polypyrrole occurs via the NH bonds which are absent in poly(N-methylpyrrole).
